页面代码:
public class FiveActivity extends Activity { private TabLayout mTabLayout; private ViewPager mViewPager; private LayoutInflater mInflater; private List mTitleList = new ArrayList<>();//页卡标题集合 private View view1, view2, view3, view4, view5;//页卡视图 private List mViewList = new ArrayList<>();//页卡视图集合 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_five); mViewPager = (ViewPager) findViewById(R.id.vp_view); mTabLayout = (TabLayout) findViewById(R.id.tabs); mInflater = LayoutInflater.from(this); view1 = mInflater.inflate(R.layout.activity_main, null); view2 = mInflater.inflate(R.layout.activity_main, null); view3 = mInflater.inflate(R.layout.activity_main, null); view4 = mInflater.inflate(R.layout.activity_main, null); view5 = mInflater.inflate(R.layout.activity_main, null); //加入页卡视图 mViewList.add(view1); mViewList.add(view2); mViewList.add(view3); mViewList.add(view4); mViewList.add(view5); //加入页卡标题 mTitleList.add("No:1"); mTitleList.add("No:2"); mTitleList.add("No:3"); mTitleList.add("No:4"); mTitleList.add("No:5"); mTabLayout.setTabMode(TabLayout.MODE_FIXED);//设置tab模式,当前为系统默认模式 mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(0)));//加入tab选项卡 mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(1))); mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(2))); mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(3))); mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(4))); MyPagerAdapter mAdapter = new MyPagerAdapter(mViewList); mViewPager.setAdapter(mAdapter);//给ViewPager设置适配器 mTabLayout.setupWithViewPager(mViewPager);//将TabLayout和ViewPager关联起来。 mTabLayout.setTabsFromPagerAdapter(mAdapter);//给Tabs设置适配器 } //ViewPager适配器 class MyPagerAdapter extends PagerAdapter { private List mViewList; public MyPagerAdapter(List mViewList) { this.mViewList = mViewList; } @Override public int getCount() { return mViewList.size();//页卡数 } @Override public boolean isViewFromObject(View view, Object object) { return view == object;//官方推荐写法 } @Override public Object instantiateItem(ViewGroup container, int position) { container.addView(mViewList.get(position));//加入页卡 return mViewList.get(position); } @Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView(mViewList.get(position));//删除页卡 } @Override public CharSequence getPageTitle(int position) { return mTitleList.get(position);//页卡标题 } }}
项目页面(个人笔记。可忽略):
public class SaleRankingActivity extends VolleyActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.sale_rangking_activity_layout); ActionBarUtil.setup(this, R.string.sale_ranking); int position = getIntent().getIntExtra(EnumIntentKey.SELECT_POSITION.toString(), 0); TabLayout tabs = (TabLayout) findViewById(R.id.tabs_square); ViewPager pager = $(R.id.vp_square); pager.setOffscreenPageLimit(2); FragmentPagerAdapter adapter = new FragmentPagerAdapter(getSupportFragmentManager()) { private String[] titles = getResources().getStringArray(R.array.ranking_type); @Override public Fragment getItem(int position) { if (position == 0) { // 专场提醒 return SaleRankingListFragment.newInstance(0); } else { // 卖家提醒 return SaleRankingListFragment.newInstance(1); } } @Override public CharSequence getPageTitle(int position) { return titles[position]; } @Override public int getCount() { return titles.length; } }; pager.setAdapter(adapter); tabs.setupWithViewPager(pager); pager.setCurrentItem(position);//推断是从哪跳进来的 }}
